MAGAZINE TOOL HOLDER.

Application led March 7, 1921. Serial No. 450,146.

To all whom it may concern Be it known that I, ANDREW ELnisoN, a subject of the King of Sweden, residing at Detroit, in the county of rayne and State of Michigan, have invented certain new and usefulV Improvements in Magazine Tool Holders, ot which the following is a specitication, reference being had therein `to the acompanying drawings.

This invention relates to improvements in tool holders, ypertaining more particularly to structures of the magazine type although it is to be understood that while the invention contemplates a holder adapted to carry a plurality of tools as a reserve to meet the various eXigencies of use, the structure is notlimited in this respect since it can be use 'd in connection with a single tool.

The invention is especially adapted to use in connection with screw driver blades or blanks, andl for purposes of illustration, the invention is described in connection with this particular use.

The invention is designed to provide a construction of great strength and capable of exerting a maximum torsional pressure upon the screw being set or unscrewed without liability of damaging or straining the tool or its holder.

A further object is to provide a holder for the blade in such form as to permit of ready substitution of one blade for another also to permit of the use of blades in various positions. In addition, the invention is designed to permit of the use of a blade of simple structure and capable of being manufactured at a relatively low cost and of' such characteristics as permit of ready substitution of one blade for another.

A further object is to provide a construction which is simple and efficient in operation durable in construction, and which can be manufactured at a relatively low cost.

. To these and other ends,fthe nature of which will be readily understood, as the invention is hereinafter disclosed, said invention consists in the improved construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed yout in the appended claims.

In the accompanying drawings, in which similar reference characters indicate similar parts, in each of the views,

The invention consists primarily in a hollow open ended member -a-, a tool carrying member -b-, having a shank JY- detachably connected thereto, a cap -c andl blades -d-, the tool being preferably completed by a small wrench ot' sheet metal adapted to permit of securing the removal of the shank or stem bfromthe member -b-. i

Member -ahas av body port-ion which may, if desired, be flute'd, as shown 1n Fig. 2, the body portion being provided with an internal washer-like member 16 which is secured within the body portion by suitable means, such for instance, as pins 17, member 16 serving to form the bottom of a chamber 18 within which the reserve tools are located, this chamber forming the magazine for the tool. Member 16 also serves as a stop to limit the inward movement of member bas presently described. Y

Miember 0bbeyond partitions 16 is preferably brought into a cross sectional area less than that of the body portion 15; if the member aL- be of metal, this reduced portion, indicated at 19, may be drawn or otherwise produced. The portion 19 has an internal coniiguration which is of non-circular contour` the particular contour shown being that of a hexagon, although it will be readily understood that the particular form of the contour may be varied, as may be found desirable, the hexagonal form being a vconvenient formA and not requiring any special manipulation of member -bwhen the latter is being inserted.

The end of portion 19 is open, as is the end of portion 15, the-latter being closed by the cap -0- which forms the cover 'lor the magazine, cap -0- and bodyv portion 15 having no threaded engagement, the cap being tree to rotate relativetoportion-15, bcing held in position by being threaded on to shank' orI stem -b-,' as shown in'F'ig. 1.` In theembodiment shown, member -bis'shown as a solidl piece ot'- material, excepting; the slot presently referred to, this being a'preferredI arrangement, although the member may be changed in this respect, as for instance by being hollow.y However, I prefer to form the member ofI stock material, thus givingthe men'ibe'r'the characteristic of a uniform cross sectional cont-our from: end

to end of themember, this contour being complemental to thatof the interior of porL ton` 19 o member -a-. 'Member-fb* has'a length approximately equal to the distance between partition It# and' the open end 4ort-he portion 19, although the member may varyin l'engthfthe drawings showing the member asy projecting slightlyl beyondl the endZ of the I )orti'onVV 1'9'.,

Member and its shank or stern are 'preferably detach-ably connected together, tiie-st'embeing in the tornr of arodwhich is threaded-Vat its opposite ends, the inner end being threaded' into member JP- the outer threaded' end being adapted' to be threaded fto capo-. The connection between membel-'or-bloeli "-b-f and its stem is onethatis not ordinarily disengaged, andv henceit is desirable thatrthe connection be made tight, andfor this reason the stem may he? providedf with a fiattened portion'tZ()r which can beengaged by a suitable wrench for the purvpose-of:tigl-itenilfrgY the stem i'ntoI the block'.

1 s will be seen member -b is heldI in proper position by cap '-c, the-latter be- Aivigit'hreaded uponthe thread end of stem L4-s and since the capy carries al flange which engages the endl of body portion 15, it'wili be-understood that rotative movement ofthe ca willfserve-to draw tlie-membcror block inward into contact withthe partition 16. thus holding the parts' firmly `together. While member -bfts- Within 19I of member w with Ia reasonably tight fit, the fit is sufficiently loose-'to permit outward movement.` of the member when permitted., by unscrewing cap 6b- And,l infthis connection', the particular arrangement of the cap and stem with? the body'portionl'fpermits of a ready removal of member '-b-, this result being; readily had by"giving cap -0- a few revolutions,

'thus withdraw-ing the cap fiange from contact with the head of the body portion 15,

then striking t-he cap to drive its flange to contact with the body portion 15, and thus project the advance endl of member b-. This operation is then repeated, thus projecting member --b-, by a progressive advancement, until the cap has been unthreadmay engage the threads of the stem after 'l which a rotative movement ,ofJ the cap will serve to draw the member toits housed tion. f

The blades darey preferably made from fiatstock, as for'instance spring steel, these being generally of uniform thickness, excepting that the outer end is subjected to pressure soas to produce the working end ofthe blade, this particular portion being indicated at 21, the tool itself being designed to provide for theuse of blades for different purposes It wili bereadily understood that the thickness of portion 21 will de -nd upon the particular use which the bla e is to haver" For instance, one blade may have a portion comparatively thin, while another blade may have it of considerably7 greater thickness, these diiierences-'beingdesigned to accommodate, for instance, screw heads of different sizes, and which have kerfs of different widths,` AndinV this connection, it maybe desirable to vary the width of the blades at' the portion l211,. Figs. 5 and? 6 showing how this may lbe done; 1

The opposite end ot* the blade is1 preferably of a width approximating that of the thickness of member in` one of itsicross sectional diinelisions,l and this width extends for a portion of the length ofthe blades, so that when the blade: is inserted withinthe n'iember it will' practieaily extend throughout thisl particular dimension and be held againstl movement in the direction o its transverse length, this result being attained by reason of the fact that this particular portion ofthe bladel is then housed within the portion 19 of Athe member -a-. Member -b`-, which receivesthe blades (Z-, is provided with va. longitudinal* Slot or keri" 22 which extends inwardly fromits outer endv a desired distance. It may be readily formed by simply sawing orcutting the member with the sawy cut extendin across the axis ofthe member, the kerffhafv ingy preferably the samewidth as the' width of the blade,V the arrangement being such that thebladeswill fit Within the korf without play, but permit of remova'l when desired. y I y To retain the blade in position, the'biade yis provided with one or moreP-preferably two-*projections 23 near its inner end, these being provided in a simple manner by the insertion of rivets, the heads of which project above the plane of the sides of the blade. To receive these projections, I provide one or more enlargements 24 to the lierf or slot 22, this being provide-d by the use of a suitable drill or instrument having a diameter greater than the width of lrerf 22.

I have shown member ZJ- as having two of these enlargements, either of which can be employed by simply withdrawing member from member -aand then inserting the blade intothe slot in such position that the projections 23 pass into these enlarge-y ments. Since there are two projections 23 preferably employed, it will be readily understood that the blade when inserted will be held from rocking movement. Generally the projections will be placed within the outer enlargements, as shown in Fig. 1, thus providing a considerable projection of the blade. However, in some classes of work it may be desired to restrict the amount of projection of the b-lade so as to avoid springing or other difficulties in which case the projections 23 may enter the inner enlargements as shown in Fig. 2, the uniform thickness of the blades and the uniform width of the slots permitting the blade to be properly inserted tolprovide either engagement. It may be desired to render the tool applicable for use under conditions where aI leverage action can be had, and for this reason I prefer to provide an additional enlargement 25 which extends along the axis of member ZJ to the bottom of slot 22, enlargement 25 being designed to receive the projections 23 when the blade is inserted with its length transverse to the length o-f member '-b-, as shown for instance, in Fig. 7, thefblade being inserted by movement in the direction of length of the member. If moved to the bottom of slot 22, Aand the free end of member -bthen placed in the portion 19, as indicated in Fig.v 7, member -f-, member band stem -bprovide a long handle which can be used for providing a long leverage or purchase for manipulating the tool. This leverage can be produced at one end only if the member -bbe not re-inserted within member mfr-. And, a comparatively short handle may be produced by removing stem ;b-. And, if desired, member -?i-, if stem -ibbe removed, can be employed for a. small size screw driver, as shown forinstance,` in Fig. 6, the blades being inserted within the transverse enlargements.

As will be seen, the particular arrangement of the parts is such as to permit of production in a simple manner and at low cost for labor, the member -abeing the more expensive part to be produced, this member, however, being capable of production at a comparatively low cost.Vv The tool is of a form to be very powerful in action, since the simple form of the blades permits of the use of high grade steel, and the non-ciroular conformation of the contacting faces of member and ZJ- is such as topermit of maximum pressure being applied on the tool to produce the desired result without liability of damaging the tool. And since all of the blades can be readily carried within the magazine portion 15, it will be readily understood that the tool can be readily carried in a tool chest without taking up an excessive amount of room. As will be readily understood in comparing Figs. 1, G and 7, the arrangement'is such as to be applicable for use in many different relations Vin each of which there is present a tool which is of maximum efficiency.

.l/Vhile I have herein shown and described a preferred embodiment 'of the invention, it will be readily understood that changes and modifications therein may be found desirable or essential in meeting the various exigencies of use, and I desire to beunderstood as reserving the right to make any and all such changes and modifications as may be found desirable or necessary insofar as the same may fall within the spirit and scope of the invention as expressed in the accompanying claims when broadly construed.
